i too bought the n800 with the hopes it could stream sirius. as it was mentioned bfore there is an app called SiriusWM5 for pocket pc that works perfect. its really only a frontend to get past the authenication on the sirius site. its not a player, it actually just sends the stream to the built in WMV player. can ppc apps be ported over to linux? or atleast be used as a starting point? also, siriuswm5 is free.
